The roster is already constructed to basically turnover this offseason and next with how the contracts are. I wouldn't mind them getting anything they can for older guys these next two seasons, but they definitely aren't going to make the playoffs and I think a "blow up" will just happen naturally by not re-signing expiring deals these next two offseasons (or I hope).
If I were to play armchair GM.... this offseason let Kane, Fischer, Petry and Motte walk. Bring over ASP, bring over/call up MBN and/or Danielson. Throw a bunch of money at Mikko Rantanen. Look to sign someone like Dante Fabbro as ASP insurance if he needs to go to the AHL to get used to ice size. Trade Lyon before the deadline this year and then call up Cossa in the offseason.
Next offseason after that, let Tarasenko, Veleno, Chiarot, Holl and Gustaffson walk elsewhere. Sign Edvinsson to a long term deal. Hopefully Mazur, Wallinder and maybe Buium are ready for a taste of the NHL. Maybe this upcoming draft we get a really good player that could be in the mix. Pray one of Karpizov, Connor, Necas, Eichel, or Kempe hits free agency especially if we don't sign Mikko Rantanen last offseason. Sign a defender or two to ~2 year deals, hopefully with a more emphasis on playing defense. Make Cossa the starter.
